Iris reticulata 'Painted Lady' is a delicate dwarf iris with elegant pale blue flowers highlighted by contrasting deep blue and yellow markings on the falls. Flowering very early in the year, sometimes from January onwards in mild conditions, it is a superb bulb for bringing colour to the garden while winter is still giving way to spring.

Growing to just 10-15cm tall, 'Painted Lady' is ideal for rock gardens, gravel beds, alpine troughs, pots and the front of sunny borders. Its refined colouring gives it a particularly light, fresh appearance, while the intricate markings reward close inspection.

About Iris reticulata 'Painted Lady'

Iris reticulata cultivars are among the earliest irises to flower, often emerging while much of the garden is still dormant. 'Painted Lady' is particularly attractive for its soft, almost icy blue flowers, which are given extra definition by darker blue markings and a vivid yellow signal on the falls.

The flowers rise above narrow, upright foliage and have the classic Iris form in miniature. Their soft colouring makes them particularly effective in winter and early spring light, where they can be enjoyed alongside crocuses, snowdrops and other early bulbs.

Very Early Spring Flowers

'Painted Lady' can begin flowering from early January in favourable conditions, with blooms continuing through the late winter and early spring period. Depending on weather and location, flowering may extend into March or April.

This long potential flowering window makes it especially valuable for gardeners looking to add interest before the main spring display begins.

Where to Plant Iris 'Painted Lady'

Choose a sunny position with excellent drainage. Reticulated irises perform best where the soil is moist while they are actively growing but does not remain wet during their dormant period.

Rock gardens, gravel gardens, raised beds and alpine troughs are especially suitable. They also work beautifully at the front of a sunny border, where their small flowers will remain visible rather than being hidden by larger plants.

How to Plant Iris reticulata Bulbs

Plant the bulbs in autumn approximately 8-10cm deep and around 5-10cm apart. Position the pointed tip upwards and cover with free-draining soil.

For the strongest effect, plant several bulbs together in groups or informal drifts. In heavier soil, adding horticultural grit around the planting area will improve drainage and reduce the risk of bulbs rotting.

Growing 'Painted Lady' in Containers

'Painted Lady' is an excellent choice for pots and containers because of its compact size. Several bulbs can be planted together in a shallow pot or trough to create a concentrated display of pale blue flowers.

Use a free-draining compost and make sure the container has adequate drainage holes. Pots can be positioned in a bright, sunny place where the flowers can be viewed at close range.

Height and Spread

Iris reticulata 'Painted Lady' reaches approximately 10-15cm tall when flowering, with an individual spread of around 5-10cm. Over time, established bulbs may gradually increase to form small clumps.

After Flowering

Once flowering has finished, leave the slender foliage in place and allow it to yellow and die back naturally. The leaves continue to feed the bulb and help build up reserves for the following year.

After the foliage has disappeared, the bulbs enter summer dormancy. A relatively dry resting period is beneficial and helps maintain healthy bulbs.
